These ASTM A182 Duplex Steel F51 Threaded Flange are available from Hex to forge Inc, a reputable source and manufacturer. Our company offers a unique selection of flanges at a reasonable price. We manufacture Duplex Steel F51 Threaded Flange in various alloys, materials, standards, and specifications to meet industry needs. Duplex Steel ASTM A182 F51 Threaded Flange is a popular duplex steel type with ferritic and austenitic microstructure. The raw material is selected according to established worldwide material standards and rigorously tested before usage. As a result, our entire manufacturing is completed following established industry norms and standards.

Threaded flanges, also known as screwed flanges, feature a male thread that matches the male thread on the pipe and a thread within the flange bore that fits on the tube. This joint connection is quick and easy to use, but it is not ideal for applications that require a lot of pressure or heat. Duplex Steel F51 Threaded Flange has a nominal chemical composition of 22 per cent chromium, 3.2 per cent molybdenum, 5% nickel, and additional alloying elements, including manganese and nitrogen. It possesses good general and local stress corrosion resistance, high strength and impact toughness. The Astm A182 Duplex Steel F51 Threaded Flange is heat-treated with annealing temperatures from 1868 to 2012°F. As a result, the flanges are interchangeable and valuable. The minimum tensile strength and yield strength of the ASTM A182 F51 Duplex Steel F51 Threaded Flange are 620 MPa and 450 MPa, respectively.
